Wide field fundus imaging is needed to diagnose, treat, and follow-up patients with retinal pathology. This is more applicable for pediatric patients as repeated evaluation is a challenge. The presently available imaging machines though provide high definition images, but carry the obvious disadvantages of either being costly or bulky or sometimes both, which limits its usage only to large centers. We hereby report a technique of fundus imaging using a nasal endoscope coupled with viscoelastic. A regular nasal endoscope with viscoelastic coupling was placed on the cornea to image the fundus of infants under general anesthesia. Wide angle fundus images of various fundus pathologies in infants could be obtained easily with readily available instruments and without the much financial investment for the institutes.

Visual loss occurred after subcutaneous silicone-oil injection for cosmetic purposes. To our knowledge, this is the first instance of amaurosis caused by a subcutaneous foreign-material injection that spared the central retinal artery and affected portions of the posterior ciliary-artery distribution, including a probable cilioretinal artery. The visual-field defects produced allow a rare opportunity to view the distribution of the human posterior ciliary-artery circulation by means of this in vivo pathologic embolic process. The facial arterial anatomy pertinent to ocular embolism is also discussed.

A family had the following manifestations of Waardenburg's syndrome (WS): prominent nasal root, white forelock, premature graying of the hair, freckled pigmentation of pale skin, hypoplastic heterochromia irides, heterochromia of the ocular fundi, congenital sensorineural hearing loss, and autosomal dominant heredity. This family differs from those previously reported in that none of its members showed dystopia of the inner canthi or lower puncta. In addition, four siblings had the combination of hyperopia-estropia-amblyopia, as well as ocular albinism, manifested by foveal hypoplasia and transilluminable irides. Observations on this family support prior suggestions of heterogeneity in WS.
